Science Olympiad Solar System Div B 2007 Joshua Haislip Event Parameters Time Limit: around 50 minutes Team: two students Materials allowed: Four-function calculator Hand-written, typed, computer generated resources (including books) All resources must fit within area of 12 X 12 X 3 Materials NOT allowed:

PDA, Cell Phone, any Electronic Devices Format Students will have a series of activities to work on at a single station or may move from station to station. Questions should be formatted to utilize science process skills: inferences, predictions, problem solving, observations, formulating and evaluating hypotheses, interpreting data, and graphing. request this poster http://chandra.harvard.edu/edu/request.html Stellar Nurseries

Shockwaves from distant supernovae or gravity from nearby stars can trigger collapse. Consists of dense regions of molecular hydrogen around 3.5 light years Pillars are left after erosion from the intense ultraviolet radiation of nearby, bright stars Evaporating Gaseous Globules

Protostars and Protoplanetary Disks As gas collapses it heats up 15 times Neptunes orbit Before nuclear fusion and hydrostatic equilibrium is achieved, this ball of gas is known as a protostar The disk of swirling dust and

gas orbiting this protostar/star is called the protoplanetary disk T Tauri Star Forming System NICMOS Peers Through Dust to Reveal Young Stellar Disks. A View of IRAS 04302+2247 Sun-like Star

Currently 70% hydrogen, 28% helium, and 2% other metals Fusion of hydrogen into helium is taking place in core 700 million tons of hydrogen are converted to helium each second Red Giant When solar-type stars run out of hydrogen in the core, they cool and begin to collapse

Collapsing causes temperature to rise, igniting a shell of hydrogen around the core Star expands over 100 times its original size, core collapses further igniting helium fusion The surface of our sun might swallow the Earth when it becomes a red giant Planetary Nebula After helium is depleted in core,

star blows off outer layers leaving behind hotter star High speed stellar winds from the new hot star slam into previously ejected material creating the nebula White Dwarf The core will eventually collapse to a white dwarf Equations Keplers Laws:

1: The orbit of a planet/comet about the Sun is an ellipse with the Sun's center of mass at one focus 2: A line joining a planet/comet and the Sun sweeps out equal areas in equal intervals of time 3. The square of the periods of a planet is proportional to the cube of its semimajor axes. 2 4 Newton determined the constant of proportionality: T r3 GM total where:

2 T = planet's sidereal period r = radius of the planet's circular orbit G = the gravitational constant = 6.67 *10 M = mass of the sun 11 Weight Equation (remember that 1 lb = 4.45 N): m3 kg * s 2

F G m1m2 d2 Suggestions: Make organized notebook of objects in the solar system and their properties (ie. mass, average distance from the sun, composition, etc.) Teach scientific notation and approximation! Many students waist a lot of times typing in the number 28389490302843848392933848. In astronomy, this can be approximated as 2.84 * 10^25.

Visit Morehead Planetarium and let me know when you are planning on coming Schedule a solar system walk this will teach scales, review planet properties, as well as give the students a sense of the size of our solar system Do not plan on learning everything! This will only serve to overwhelm you Most Importantly: Get the students excited about astronomy! Wikipedia Use Wikipedia to obtain organized tables of information about planets and other objects in the solar system

Also zoom in on planets and Messier objects to see them as they would look through a telescope. http://www.stellarium.org/ Test your students Stellarium skills with my Stellarium Challenge Test your students understanding of Keplers third law, as well as the weight equation with my lab Measuring the Mass of Jupiter:
